THREAD GUARD CASTER Filed Nov. 17, 1928 IN VEN TOR. HWP/FY 6. A WSCHKE, JFK
Patented Nov. 4, 1930 UNirE D- starts PATENT aorrics HARRY o. NASCHKE, JR, or PHILADELPHIA, PENNSYLVANIA, Assreivon To Mortars TRUCK AND WHEEL CO. INC., OF PHILADELPHIA, PENNSYLVANIA, A CORPORATION on rENnsYLvAnm "rrrnnangeuaan cAsrEn Application, filed November 17, 1928. Serial No, 320,096.
My invention relates to novel construction of a caster which'is adapted'and designed to support racks, trays, trucks boxes and thelike and is especially designed to prevent the 5 adhering and winding 'upon'the caster axles of threads, lint, shavings and the like, which may be caught up onthe floor over which the casters travel. I v i A further'object of my inventionis to 1 provide a novel caster housing which is made in sections which are substantially duplicates and are provided with'peripheral, inwardly converging, stationary, outer annular walls, whose peripheral edges are overhung by the outer peripheral edges of the caster'so that there isnoliability of threads, lint or other debris being taken up by the tread of the caster or wound upon the axle thereof, since the contiguous peripheral outer sloping wa'lls of the housing sections will tend toguide threads, lint and the like away from the caster proper, and-from the interior or the axle or bearings thereof. W
It further consists of a caster having the novel housing hereinabove described and an axle joining the housing sections in combination with a'ball bearingelement common to said axle and the caster, whereby friction is reduced to a minimum; t p r 'It further consists of a: novel construction of a sectional caster housing, the base sectionsof which are adapted to interlock.
A further object of myinvention isto simplify the mounting of the caster wheels'and to provide aconstruction of :caster -wheel mounting equipped witha novelroller bearing which can be readily lubricated. s It further consists of other .novel features of: construction and advantage, all of which 140 will be hereinafter pointed out in the, specification and claims appended hereto.
For the purpose of illustrating my inventionI have shown in the accompanying drawings one form thereof which is at present preferred by me, since the same has been found inpractice to give satisfactory and reliable results, although it is to be understood that the various iinstrumentalities of Which my invention consists :can be variously ar ranged and organized and that my invention is not limited to theprecise arrangement and organization of'the inst'rumentalities' as herein shown and described.
t Figure 1 represents aside elevati'onof'a thread guard caster, embodying'my 'invention.
Figure 2 representsa section on lin 2 2 of Figure 1.
ure 1. 1
Figure '4 represents aside elevationshow tion of one of the caster housings, with' the caster seenin Figure 4:-'removed.- i
Figure 6 represents a section on line p of Figure 5. g
-- Referring to the drawings inwhich similar numerals of reference indicategcorre-l sponding parts, g Y 1 1 designates my novel construction of caster, the same comprising two outer hous-- ings 2 and 8 and the caster 4, and since the construction of said housings is substantially the same,- a description of one will sufice for both. 'Eachhousing section as 2, is provided with the base portion 5, from which'depends the downwardly converging arms6 which merge into the housing body or annular, inwardly converging peripheral portion -or: wall 7,
Figure d represents a plan view" of eej which iscast or integralwith 'the'central thickened portion 8 of said housingsection which has the hole 17 through whichpasses' sleeve having its ends positioned in the seats 22 in thethickened central portions 8 ofthe housing sections, as will be understood from Figure 2; said sleeve forming apart of the ball or roller bearing 16, which is composed of the rollers and cages therefor as is customary', said roller bearlng being confined between the sleeve 15 and the hub portion 10 'of the caster 4, as will be understood from Figure 4.
In F igures o-and 6, there-is clearly'shown one of the seats 22 in which the ends of the sleeve'15 are positioned, the hole 17 being for the passage of thebolt or axle 9. There is a slight depression asindic'ated at 18 in the outer wall of each housing section for the reception of the head or nut of the bolt or axle 9. As will be apparent from Figure 3,
I the base member 5 is provided with V-shape seats 19 which receive'the V-shapeprojections 20, so thatthe' housing sections when assembled, together and bolted through the holes21'to the rack, truck orthe like will in ware assembled. The parts are shown in as-- conjunctionwith thebolt or axle Qcause all the parts accurately to align when the same sembledposition in Figures 1,2 and3, and it f will be apparent that whenit is desired to have accessto the interior it is only necessary to' unscrew the nut from the bolt or axle 9 whereupon the parts can be readily sepas rated and thelball bearings or caster 4 and 'to the interior of the caster bearings thereof.
the housing sections are'r'eadily accessible. When it is desired to assemblethe parts, it is only f'necjessary to place the housing sections in juxtaposition as seen in Figures 2 and 3,
with the caster and ball bearings in the posi-' tion shown and then toinsert the bolt or axle 9 and tighten the nut thereon. 3 i
, Idesire to call especial attention to the fact that by reason of the caster edges '13 overhanging the peripheral edges 14 of the housing sections, axsufliciently nice fit is formed so that ,in practicev while the caster 4'can freely revolve, threads, lint, dirt, shavings or" the like are prevented from having ingress or the axle or K'In practice, Whatever threads, lint,shavings or the like are'caught up byithe tread 12" of the castertslide down the inclined walls? of the sectional housings and will not tend to wraparound the a'x'le'9 orto clog the a g 7 same orthe ball bearings "therefor.
A ention' is called to the factthat the tractimepiece 0fthe caster; which isthe an r the friction surfaces of the roller bearings" of tread 1"2,'is'-' an appreciable distance from sothat-thetorque calculated at the friction surfaces is relatively large. v
ltlis apparentthat my novel device can be readily: expeditiously made ofcastin-gs or stampings, and that there is a minimum amount of machining or tru'ing .up required and that the, number of parts is also reduced. to a minimum. The housing sections comprising themembers 5, 6, 79nd 8 being preferably forrned integral re'sult in a rigid. and durable construction which -w'ill --lastin-' ters Patent, 7 isz T? definitely even under the hard usage to which these devices are subjected;
fitted to conform to the inside 'of'ther'ir'n of 1 the wheel 4: thereby completely encasing the wheel inside of thetread thereof. The sleeve or steel tubing 15 acts both as an axle and agsp'acer and the roller bearing turning thereon obviously reduces friction to a" mi'ni 5 mum. The tubing 15 is: held rigid by the bolt 9 passing therethrough and through the sides of the, brackets which bolt also completes the assembly of the wheel, and
the ends of the tubing being set in the seats or recesses 22 or in the inside of 'the brackets takes allQstrain olf the bolt and acts as-an axle as is evident. 5 I
I am aware that the invention may be em=- bodied in other specific forms withoutde parting from the spirit or essential; attri butes'thereof, and I therefore desire the present embodimentto be considered. in all respects as illustrativeiand vnot restrictive, reference being had to'the. appended claims ratherthan to the'foregoing description to 7 indicate the scope of'the'invention,
5 Having thus described my invention what I claim asnewfand desire to sec ureby Let-J 1. In a device of'the character stated,
